METHODOLOGICAL INFORMATION

1. Description of methods used for collection/generation of data: 
Please see Dambrogio, Ghassaei, Smith, Jackson et al, Unlocking history through automated virtual unfolding of sealed documents imaged by X-ray microtomography, Nature Communications.

2. Methods for processing the data: 
Letterlocking data was collected over many years and in many collections, and systematised as the Categories and Formats chart. For the purposes of this article, original archival documents in the Brienne Collection were examined in close detail, photographed, and modeled. Using these models and originals, physical data were mapped onto foldable instructional resources, and videos were made documenting the letterlocking process. 

3. Instrument- or software-specific information needed to interpret the data: 
N/a.

4. Standards and calibration information, if appropriate: 
N/a.

5. Environmental/experimental conditions: 
N/a.

6. Describe any quality-assurance procedures performed on the data: 
N/a.

7. People involved with sample collection, processing, analysis and/or submission:
